tion (Y page 65).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EB Dhas malfunctioned, the braking system
remains available with full brake boosting
effect .However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident .You should therefore adapt your
driving style to the different handling charac-
teristics.
X Observe the notes on warning and indicator
lamps (Y page 275) as well as display mes-
sages (Y page 235) (4-button multifunc-
tion steering wheel) and ( Ypage 240) (12-
button multifunction steering wheel). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 177) and
hill start assist (Y page 140). For further

Brake
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 65). PRE-SAFE
®
Brake can help you to minimise
the risk of a frontal collision with a vehicle
ahead or reduce the effect sofsuch a colli-
sion. If PRE-SAFE ®
Brake has detected a risk
of collision, you will be warned visually and
acoustically as well as by automatic braking.
PRE-SAFE ®
Brake cannot prevent a collision
without your intervention.
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in fron tis too short for
the speed at which you are travelling. The
· distance warning lamp then lights up
in the instrument cluster.
R you are rapidly approaching the vehicle in
front. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
If the driver and passengers have fastened
their seat belts, PRE-SAFE ®
Brake can also
can also perform the following at speeds of
above approximately 30 km/h:
R brake the vehicle automatically from a
speed of up to approximately 200 km/h
R trigger preventative passenger protection
measures (PRE-SAFE ®
) (Y page 50)
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. To end this,
you can either depress the accelerator pedal
further, activate kickdown or release the
brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you drive slower than approximately
15 km/h.
R you manoeuvre to avoid the obstacle. Driving safety systems
